METALLIC LATHING- Patented Feb. 24,1891.

UNITED STATES PATENT OFF C LONGLEY LEVIS SAGENDORPH, OF PHILADELPHIA,PENNSYLVANIA.

METALLIC LATHING.

SPECIFICATION forming part of Letters Patent No. 447,085, dated February24, 1891.

Application filed October 4,1890. Serial No. 367,061- (No model.)

To all whom it may concern:

Be it known that I, LONGLEY LEWIS SAG- ENDORPH, a citizen of the UnitedStates, residing at Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented certain new and useful Improvementsin Metallic Lathing, of which the following is a specification,reference beinghad to the accompanying drawings, forming a part thereof.

The object of my invention is to provide a metallic lathing-sheet soformed as to afford an ample and secure locking-surface for the mortarto adhere to and at the same time stiffen or strengthen the sheet, aswill be apparent from the description hereinafter given.

In the accompanying drawings, Figure 1 is a perspective view of aportion of a lathingsheet embodying my invention and as preferablyconstructed. Fig. 2 is an end View of the lathing-sheet shown in Fig. 1.Fig. 3 is a cross-section taken at the dotted line 5c 00, Fig. l, withthe mortar applied thereto, illustrating the manner in which the plasteris keyed to the sheet. Fig. 4, illustrates a slight modification of myinvention, being an end view of a portion of the sheet.

My improved metallic lathing consists of a sheet of suitable metalcorrugated, with loops A cut and forced outward from the concave surfaceof each corrugation, as shown. It will be readily seen that both facesof my improved lat-hing are the same and are capable of being reversed.The loops A are formed by cutting a slit in the metal at each sidethereof and forcing the metal outward between said slits, the apex ofeach loop preferably terminating below the apex of the main adjacentcorrugations B, as shown. The corrugations B are preferably circular inoutline, but may be formed V- shaped or rectangular, as shown in Fig. 4.

The plaster 0 may be applied to either face of the lathing-sheet,whichever face may chance to be outward when the sheets are applied, andsecured to the walls or ceiling or other portion of the buildingdesigned to be plastered.

The advantages of my new and improved lathing are many and apparent. Inthe first place, a very secure lock or key is afforded for the plasterto adhere to, as will be seen by reference to Fig. 3. The plaster whenapplied to the sheet is forced in against the loops, which curve inward,said loops causing the plaster to spread out at each side thereof, asshown, and thus cause a secure lock at the rear side of the sheet, theplaster being looked around the loops, which curve outward, as shown insaid figure, thus affording double security. The main corrugations orribs 13 tend to stiffen and strengthen the sheet and at the same timepermit of its being bent around girders or oval surfaces withoutimpairing its locking qualities. The sheet of lathing thus formed iseasily applied and handled, no sharp points'or corners being present tolacerate the operators hands.

The lathing aforedescribed is designed as an improvement on the lathingpatented to me February 25, 1890, No. 422,318, and is superior thereto,on account of the locking-surface produced.

What I claim as new, and desire to secure by Letters Patent, is

1. A corrugated lathing-sheet having loops cut and forced outward fromthe concave surface of each corrugation, as and for the purposesspecified. I

2. A corrugated metallic lathing-sheet having loops cut and forcedoutward in opposite directions in alternate corrugations, said loops attheir end portions being integral with the body of the sheet, as setforth.

3. A corrugated lathing-sheet having loops or retaining portions cut andforced outward from the concave surface of each corrugation, the apex ofeach loop or portion terminating below the apex of the adjacent convexcorrugations, substantially as set forth.

4. A corrugated lathing-sheet having loops out and rounded outward fromthe concave surface of each corrugation, integral therewith and at rightangles thereto, as shown and set forth.
